False discovery rate 中文
Web错误发现率 (FDR) 本研究使用 错误发现率(False Discovery Rate, FDR)来定义阳性发现 。. FDR是常用的统计学结果判定标准,其意义是错误拒绝(拒绝真的原假设)的个数占所有被拒绝的原假设个数的比例的期望值。. 1995年Benjamini和Hochberg首次提出了FDR的概 … WebThis paper describes theoretical bounds on the quality of a fundamental Bayesian Network local-learning task in the finite sample using theories for controlling the False Discov- ery Rate. The behavior of the derived bounds is investigated across various problem and algorithm parameters.
